For the Apple products I use I can't remember the last time I had to search the web to figure something out... two instances come to mind: command-tilde was a tip from Woz, and somebody on /. suggested turning on a system option that allows me to navigate GUI menus with the KB. But both of those are years ago. Other than that, I've figured out every gesture, hot key, navigation technique that I use on the OS X and iOS products.
Coming from that world, I don't really think to search the web when I have a problem like this, I just assume that the OS is broken.
